  • Patent number: 10559429
    Abstract: The present disclosure relates to a photosensitive organic capacitor whose capacitance efficiency is increased if light is applied to the photosensitive organic capacitor, and the photosensitive organic capacitor includes an upper substrate and a lower substrate that are spaced apart by a certain interval, an upper electrode and a lower electrode that are attached to each opposing side of the upper substrate and lower substrate, an active layer that is formed between the upper electrode and the lower electrode, and an upper polarization-inducing layer and a lower polarization-inducing layer that are formed between the upper electrode and the active layer and between the lower electrode and the active layer, and that induce the polarization of charges within the active layer if light is applied to the photosensitive organic capacitor.
    Type: Grant

  • Patent number: 10529936
    Abstract: The present disclosure relates to a memory device having a hybrid insulating layer and a method for preparing the same. In detail, a memory device including a gate electrode on a substrate, a source electrode, and a drain electrode has a hybrid memory insulating layer between the gate electrode and the source and drain electrodes that is polarizable and includes a mixed material of vinyltriethoxysilane and organic matter to lead to hysteresis. According to the present disclosure, a memory insulating layer is formed as a hybrid insulating layer including a mixture of polyvinylphenol as the organic matter and vinyltriethoxysilane to complement the properties of an organic memory whereby increasing memory performance, and it stably operates at both low and high temperatures whereby having a wide usage range.
